People are worried about Ezekiel Elliott. More specifically, some legendary running backs are worried about the former Ohio State star.

Why?

Elliott, who just turned in one of the best rookie seasons from a running back in NFL history, has a knack for hurdling defenders. We saw that plenty during his Ohio State days and he did it often during his first season with the Dallas Cowboys.

Here’s proof:

But while that might land Elliott on the highlight reel, Emmitt Smith cringes when the Cowboys star takes flight.

“Get on the ground as quickly as possible,” Smith said via Pro Football Talk. “Every time I watch somebody run, I’m looking very closely, very tentatively, seeing how they fall because a lot of things happen when you fall.”

Fellow former Cowboy tailback and Hall of Famer Tony Dorsett echoed those sentiments about Elliott’s go-to move in the open field.

“He better stop that. He better stop that. He better stop that,” Hall of Fame running back Tony Dorsett said, via Charean Williams of the Fort Worth Star-Telegram. “That’s one thing that I don’t like. When you get airborne, you’re at the mercy of the hit, and sometimes you can’t protect yourself. I think as he gets older he may take that out of his repertoire.

“He needs to stop that. That scares me every time he gets airborne. I’m like oh….”

Elliott earned All-Pro honors after leading the league in rushing and scoring 15 touchdowns.

The odds of Elliott dialing his hurdling back aren’t likely, no matter how nervous it makes a few legendary backs.
